Top Picks: new discover of (1R,2R)-Cyclohexane-1,2-diamine

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: catalyst-ligand, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 20439-47-8

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， category: catalyst-ligand, Which mentioned a new discovery about 20439-47-8

The enantioselective Michael addition reaction of malonates to alpha,beta-unsaturated ketones is efficiently promoted by a combined dual-catalyst system composed of chiral thiourea and 4-pyrrolidinopyridine (PPY) in toluene. The expected Michael adducts with cyclic and acyclic enones are obtained in excellent yields and with excellent enantioselectivities.
